If you have previous experience working with a hardware in the loop system and a passion to lead a team of smart engineers, you\'ll be a great fit for this position. You\'ll be joining a team that designs, builds and runs hardware in the loop (HWIL) testing around a weapon systems flight computers and other components, including datalinks, GPS receivers, and IMUs., * Possess a BS in Computer Engineering, Electrical Engineering, Computer Science, Physics, or similar field. * Have 5+ years of experience working with hardware in the loop test beds. * Are skilled in software programming, understanding electrical signals and how embedded systems communicate. * Capable of leading a team of 2-6 (or more) engineers to design and build out a Hardware in the Loop testbed. * Are able to obtain an Interim Secret level security clearance by your start date and can ultimately obtain a Top Secret level clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship. You\'ll go above and beyond our minimum requirements if you... * Have significant experience designing and building hardware in the loop test beds. * Have experience designing high fidelity (6-dof) software simulations for flying platforms (missiles, planes, projectiles). * Have experience with object-oriented programming languages (Java, C, C++) and scripting languages (Python or MATLAB). * Are familiar with one or more of: CUDA, FPGA, software defined radio (SDR) or RFSoC, networking protocols, RF systems. * Have experience with test equipment including spectrum analyzers and oscilloscopes * Have experience with both Windows and Linux operating systems ## Description * Your primary responsibility will be leading a team of engineers to design, build, and run real-time, open-loop and closed-loop, hardware in the loop capabilities around unique weapons systems. * You will work with the government to design tests based on their needs and will lead execution of test and analysis activities. * Work with software and hardware designers to develop and implement the HWIL capability, taking care to understand requirements the specific HWIL objectives levy on the architecture. * Work with embedded hardware systems, understanding the electrical interfaces, physical interfaces, and communications protocols * Present status and results to project, program, and external sponsors * Mentor staff on HWIL designs, break up tasks as needed in chunks to fit the levels of individual staff members. * You will document code, implement CI/CD practices, setup network systems together, and communicate your needs across the team. ## Related Videos - [JavaScript?
